Flame temperature measurement through a light field camera shows an attractive research interest due to its capabilities of obtaining spatial and angular rays’ information by single exposure. However, the sampling collected is vast most them are redundant. The reconstruction process occupies larger computing memory time-consuming. We propose novel approach i.e., feature rays under-sampling (FRUS) reduce redundancy thus improve efficiency. proposed evaluated numerical experimental studies....

ABSTRACT Virtual reality (VR) immerses users in digital environments and is used various applications. VR content created using either computer‐generated or conventional imaging. However, imaging captures only 2D spatial information, which limits the realism of content. Advanced technologies like light field (LF) can overcome this limitation by capturing both angular information 4D LF images. This paper proposes a depth reconstruction model through to aid creating realistic Comprehensive...

A three-component metal catalyst was prepared and used in the process of catalytic wet peroxide oxidation (CWPO) for degradation unsymmetrical dimethylhydrazine (UDMH) propellant wastewater with H₂O₂.

Difference of convex (DC) functions cover a broad family non-convex and possibly non-smooth non-differentiable functions, have wide applications in machine learning statistics. Although deterministic algorithms for DC been extensively studied, stochastic optimization that is more suitable with big data remains under-explored. In this paper, we propose new study their first-order convergence theories solving functions. We improve the existing from both practical theoretical perspectives. On...

Due to the variety of burner structure and fuel mixing, flame temperature distribution is not only irregular but also complex. Therefore, it necessary develop an advanced measurement technique, which can provide adequate radiative information reconstruct complex accurately. In this paper, a novel multi-plenoptic camera imaging technique proposed provides from two different directions reconstructs An inverse algorithm, i.e. non-negative least squares, used temperature. The bimodal asymmetric...

The key to the variation in permeability within coal reservoirs lies stress-induced deformation and desorption-induced during coalbed methane (CBM) production. differences sample scale measurement methods between significantly affect accuracy of measurements. Therefore, order elucidate relationship adsorption-induced deformation, as well influencing factors, assess evolution prediction, this study conducted a series parallel experiments, including compression experiments under stress loading...

Deep coal reservoirs, as opposed to their shallower counterparts, exhibit characteristics of higher temperatures and pressures. These conditions affect the fracture structure mechanical properties coal, which in turn controls permeability. Substantial studies have been conducted determine effects overburden pressure on permeability, but correlation between temperature parameters/permeability remains unclear. This study focused low-rank bituminous from southern edge Junggar Basin Xinjiang....

Industrial robots have been increasingly used in the field of intelligent manufacturing. The low absolute positioning accuracy industrial is one difficulties their application. In this paper, an compensation algorithm for proposed based on deep belief networks using off-line method. A differential evolution presented to optimize networks. Combined with evidence theory, a position error mapping model realize robots. Experiments were conducted laser tracker AT901-B robot KR6_R700 sixx_CR. end...

Accurate and reliable measurements of the 3D flame temperature profile are highly desirable to achieve in-depth understanding combustion pollutant formation processes. In this paper, a measurement method for reconstruction was proposed by using light field camera. It combines convolution imaging model radiative transfer equation takes into account characteristics emission, absorption, scattering semitransparent flame. According point spread function system, number positions refocus planes...
